In VR i can see left controller only

Sorry, my english
is not good, but I’ll try to describe my problem. I received nolo. Unpacking
it. Pairing is ok – green lights on every parts of nolo components. Left
controller is ok. It buttons are works normal and I can see controller in VR.
Right controller is not ok. It buttons are works normal too, but I can’t see
controller in VR.
